Python regex compiled vs inline

compiled.py

import re
from pathlib import Path
p = Path("big.txt")
t = p.read_text()
rgx = re.compile(r"\w+")
for _ in range(10):
  rgx.findall(t)

gistfile1.txt

import re
from pathlib import Path
p = Path("big.txt")
t = p.read_text()
rgx = re.compile(r"\w+")
for _ in range(10):
  rgx.findall(t)

literal.py

import re
from pathlib import Path
p = Path("big.txt")
t = p.read_text()
for _ in range(10):
	re.findall(r'\w+', t)
